One hacker outsourced 100 break-ins to AI agents. The tab was about $5,000.

I keep saying the future won't knock first. This morning Reuters handed me the receipt. Over the past couple of weeks, a cybersecurity researcher watched a single Chinese-speaking hacker break into websites belonging to more than 100 companies — Deere, SharkNinja, and Cummins among them. The hacker did almost none of the work. He delegated the entire heist to AI agents. Here's the play-by-play, from Snorre Fagerland, principal threat researcher at the security firm NorForge. He was scanning the web for exposed instances of Cairn, an open-source AI problem-solving platform popular with hackers, and found roughly two dozen control panels running malicious work — left unauthenticated, so he could read the operation like a playbook. The campaign started around September 25 against e-commerce sites in the US, Canada, Australia, and Japan. The attacker's instructions were terse: fewer than 100 Chinese characters. From there the agents worked unsupervised — probing targets, failing, adapting. In one case, finding no weakness in a company's public app, they dug through digital records to locate an obscure control panel, found a subtle flaw in how it processed data, and tricked the server into executing malicious commands. Each successful break-in took about 23 hours of autonomous effort. Total token spend: roughly $5,000, or about $50 per hack. The stack appeared to mix China's DeepSeek with Anthropic's Claude Code. "It's not script kiddie stuff," Fagerland told Reuters. His shorter quote is the one I can't shake: "It's a new world now." The same agent capabilities shipping inside every coding tool are dual-use in the most literal sense. The gap between "AI assistant" and "AI burglary crew" turned out to be a paragraph of instructions and a few thousand dollars. Fagerland spotted several operators doing this — one stealing credit card data, another aiming agents at a crypto exchange. This isn't one weird incident. It's a proof of concept already running in production. Welcome to the new world. Audit your dashboards.
